History Sikorsky
Sikorsky CH-53K King Stallion

he Sikorsky CH-53K King Stallion (Sikorsky S-95) is a heavy-lift cargo helicopter designed and produced by Sikorsky Aircraft. The King Stallion is an evolution of the long running CH-53 series of helicopters which have been in continuous service since 1966, and features three uprated 7,500 shp (5,590 kW) engines, new composite rotor blades, and a wider aircraft cabin than its predecessors. It is the largest and heaviest helicopter in the U.S. military.

The United States Marine Corps plans to receive 200 helicopters at a total cost of $25 billion. Ground Test Vehicle (GTV) testing started in April 2014; flight testing began with the maiden flight on 27 October 2015. In May 2018, the first CH-53K was delivered to the Marine Corps. On 22 April 2022, it was declared to have passed initial operational capability. Israel has also reportedly ordered the type; other potential export customers include Japan and Germany

The CH-53K King Stallion is a heavy lift helicopter, being a general redesign of the preceding CH-53E, the main improvements being the new engines and cockpit layout. It has over twice the lift capacity and radius of action of the CH-53E, and a wider cargo hold to allow it to carry a Humvee internally. A new composite rotor blade system is also used, featuring technology similar to that of the UH-60 Black Hawk helicopter. The CH-53K is powered by the General Electric GE38-1B engine, which was selected over the Pratt and Whitney Canada PW150 and a variant of the Rolls-Royce AE 1107C-Liberty used on the V-22 Osprey.^[47] Each of the three T408 engines is rated at 7,500 shp (5,600 kW), and gives the CH-53K the ability to fly 20 knots (37 km/h; 23 mph) faster than its CH-53E predecesso
